Try this idea on for size.
After the attack on Pearl Harbor, several American pilots were shot down, being mistaken for more Japanese attackers.
If I remember correctly, on D-Day Normandy, Jimmy Doolittle flew over the area to see how the invasion was going. He flew a P38 because of its unique shape; i.e. "Hey Guys, I'm not the enemy, don't shoot at me."
Therefore, P38s should be the only plane immune from friendly puffy ack. OK, not immune but a Lightning should only have a 10% chance of being hit. Anything else, it stays the way it is.

Now is this my sense of humor

or do I have a valid point
